Procedure
Using an analogous procedure to that described in Example 36, 4-(2-fluoro-5-methoxycarbonyloxy-4-methylanilino)-7-hydroxy-6-methoxyquinazoline hydrochloride (224 mg, 0.6 mmol), (prepared as described for the starting material in Example 22), was treated with 4-bromomethyl-1,2-difluorobenzene (149 mg, 0.72 mmol) to give 7-(3,4-difluorobenzyloxy)-4-(2-fluoro-5-hydroxy-4-methylanilino)-6-methoxyquinazoline hydrochloride (90 mg, 31%). 1H NMR Spectrum: (DMSOd6) 2.17(s, 3H); 4.0(s, 3H); 5.33(s, 2H); 6.88(d, 1H); 7.11(d, 1H); 7.38(s, 1H); 7.41(m, 1H); 7.55(m, 1H); 7.62(m, 1H); 8.17(s, 1H); 8.75(s, 1H); 9.68(s, 1H); 11.15(s, 1H) MS-ESI: 442 [MH]+
